The leaves of trees turn brilliant red, yellow, and orange in fall---but not a pine tree. It is hard to tell what season it is by looking at a pine tree.
As you walk through the forest reach out and touch the tender leaves of the trees---but be careful of the pine trees. They feel more like porcupine quills.
It was a sunny vacation day on Drummond Island, I was sitting in my comfy chair on the deck reading one of the many books I had packed for vacation. I would look up every few minutes to check our bay for loons or I would use the binoculars to check Lake Huron for barges in the distance. That's when it happen,
I heard a sound the snap of a small twig to my left. I am always on the lookout for bears, so of course that was my first thought. As I slowly turned my head toward the sound, I was surprised at what I saw.

Research Project
Stain Glass Window Maker
Introduction of your Career
The sunlight peeks in through the confetti glass, saying "Good Morning, Delia". I love the stain glass window in my dining room. I have always wanted to be able to create a beautiful piece of art using glass. What would I make? How is the glass manufactured? What holds the glass together? These questions race around my brain and I hope to answer them in my research.
I wonder....
I wonder how the beautiful colors of glass are made.
Glass is made mostly of silica, which is most commonly found in the quartz stone. In addition to silica, glass also has lime and soda. The mixture is heated up to a point where it becomes molten, about 2600 F. Different materials are then added to achieve the colored glass. The recipe for green glass is to add copper oxide, for blue glass, add cobalt and for red, the special ingredient is gold. Red glass is made cheaper today by using copper.
The method used to make the glass is called flash glass. This is used in glass where it needs to be strong enough to stand up to wind. This glass is at least 1/8 inch thick. In this method, a thinner layer of clear glass is then dipped into colored glass
I wonder....
I wonder how the glass is held together.
There are two ways that stain glass is held together. One is called lead came and the other is copper foiling. The lead came has grooves that the glass is set into. All edges of the glass are placed in the lead came. Then the joints of the lead are soldered. Then a waterproof glazing compound is put all around the glass and the lead came. This helps to strengthen and protect the piece from water.
